g 186 Claim.

This invention relates to machines for binding bundles, boxes, or like,and more particularly to machines for wrapping and securing a tautbinder in band formation about a bundle, without drawing the binderacross any edge or face of the bundle. 1

An object of the invention is to provide a machine which is readilyadaptable for all conditions of service.

A further object of the invention is to provide a machine which willplace one or more bands at any desired point about a bundle and securethe same in place.

Another object of the invention is to provide a machine which is capableof binding a plurality of bundles at one time.

Another object of the invention is to furnish a machine which willtension and put a band under predetermined tension about bundles or thelike.

Another object of the invention is to provide means which, when wire isused, will so flex the wire as to cause it to lie flat against andtightly hug the sides of a bundle when applied thereto and secured inband formation thereabout.

A further object of the invention is to provide a bundle binding machinewhich, when wire is used will either coil or intertwist the terminals ofthe binder with only minor changes in its parts.

Another object of the invention is to provide bundle clamping meanswhich will effect quick and firm clamping and holding of bundles to bebound, irrespective of the size of the bundles within the range ofmovement of the bundle clamp, without the necessity of adjustment of theclamping means.

Another object of the invention is to provide bundle abutment meansadjustable relative to the bundle support, whereby bundles of varyingwidths may be properly located in binding position with respect to thebinder securing means.

Other objects of the invention will be apparent and understood from aconsideration of the following detailed description taken in connectionwith the accompanying drawings forming part of this specification, withthe understanding, however, that the invention disclosed herein embodiesnew and useful features which are not confined in any strict conformitywith the showing of the form of machine in the drawings, but

. may be modified and adapted to other forms of bundle binding machines.

In order thatthe principles of the invention may be best understood, Ihave herein disclosed expansible, or inelastic objects or material is 10bound, it being understood that certain features of the invention may beused and incorporated to advantage in other and widely differing forms,or types, of binding machines, than that herein selected forillustration, such as machines for 15' binding either compressible orincompressible bundles, packages, or the like, with wire, a flat band,rope, cord, or the like.

It will be understood by those skilled in the art, that of the variousbinding elements employed 20 for binding bundles, packages, and thelike, the use of wire has presented the most diflicult problem, due tothe diiflculty in efiecting tight hugging of the wire against the sidesand periphery of the bundle, and therefore, in selecting the 25 presentform of machine for illustrative purposes,

I have done so in order to describe and make clearly apparent the mannerin which my invention, through flexing of the wire, overcomes suchdifflculty and effects tight hugging of the wire against the sides andperiphery of the bundle.

Fig. 6 is a vertical section on the line 66 of Fig. 1 showing the mannerin which the clamp elevating cam has raised the bundle clamp or jaw tobundle receiving or bundle discharging position against the pressure ofthe clamp actuating means.

Fig. '7 is a vertical section on the line 1-1 of Fig. 1 showing anassembly of bundle binding and tying mechanisms and operative featuresthereof in the form of a complete binding and tying unit mounted on asingle standard and adapted to receive bundles advanced in lengthwisedirection, directly into binding position.

Fig. 8 is an elevation of one of the end bundle holding frames viewedfrom the outer face thereof.

Fig. 9 is an elevation of one of the intermediate or open-mouthed bundleholding frames showing the movable clamp or jaw in bundle holding orclamping position under the pressure exerted by the springs whichactuate the bundle clamp or jaw.

Fig. 10 is a fragmentary elevation of the end bundle holding frame shownin Fig. 8, looking from the other side thereof, illustrating the lowerposition of the roller, which rides on the elevating edge of the clamplifting cam, when the movable clamp or jaw is in clamping position.

Fig. 11 is a sectional view on the line i ll I of Fig. 10 showing theclamp or jaw forced into bundle holding and clamping position by powerof the pressure spring which actuates the clamp and providesadaptability to compensate for the clamping of bundles of differentsizes within the limits of yieldability of said power exerting spring.

Fig. 12 is a sectional view on the line IZ-IZ of Fig. 11 showingconstruction whereby the bundle clamp or jaw is slidably mountedrelative to the bundle holding structure.

Fig. 13 is a top plan view with parts in section of one of theintermediate bundle holding frames.

Fig. 14 is a sectional view on the line l4l4 of Fig. 13 showingconstruction whereby the bundle clamping means or jaws are slidablymounted relative to the bundle holding structure and also showing thepower actuating springs, which effect the clamping and holding of thebundle, and which springs are adapted to compensate for the clamping ofbundles of different sizes, within the limits of yieldability of saidpower exerting means.

Fig. 15 is a detail sectional view of the clutch mechanism showing theparts thereof in disengaged position.

Figs. 36, 37, 38, and 39 are diagrammatic views illustrating variouspositions of a bundle as it is rotated and a taut wire is applied andsecured into band formation thereabout, and also the oscillatorymovement of the binder wrapping and tensioning device which so tensionsand directly applies the wire, flexed, thereabout, as to cause the wireto tightly hug and lie flat against the entire periphery of the bundle,the tension and stress inherent in the wire by reason of such flexing,tending to cause the wire to press convex inwardly toward and againstthe sides of the bundle.

In the present instance, the particular machine herein is constructed todraw wire from a coil, and to flex and so wrap the wire under sumcienttension around a bundle, box, or the like, as to cause it to tightly hugthe sides of the bundle, without dragging it over any corner or edgethereof, and to tie the wire without overstraining it or causing injuryto the tie. Means are provided for flexing and tensioning the wire forwrapping about the bundle. Means are also provided for maintaining thewire taut by preventing slack therein during the operation of thewrapping of the wire into band formation about the bundle.

The machine is provided with a bundle support having a knotter or wiretwisting device disposed in fixed position below the plane of thesupport, and in the plane of wrapping of the wire about the bundle, forreceiving and uniting the wire wrapped about the bundle. Meansadjustable toward and from the twisting device are provided for locatingbundles of differing widths in proper binding and tying position on thesupport. Means are also provided for quickly, firmly and compensatinglyclamping the bundles so located, and bundles of varying dimensionswithin the range of movement of the clamp without injury to the bundlesor the machine. The wire is gripped and in tension when the twistingdevice is operated to tie the wire encircling the bundle in bandformation thereabout. Means are provided for cutting the wire thenextending from the tie to the supply. Means are also provided for timingthe operation of the means for effecting wrapping of
